If two atoms are bonded with a bond energy of 455 kJ, what must be done to break the bond?

A+b→2c when the reaction begins, the researcher records that the rate of reaction is such that 1 mole of a is consumed per minute. after making changes to the reaction, the researcher notes that 2 moles of a are consumed per minute. what change could the researcher have made to effect this change?

This is a mixture that has the same composition throughout.

You may expect bonds between two atoms which each have n covalent lonic metallic hydrogen
